What's your EDC Calculator?

Myself, I'm rockin' a TI-89 still. Hardware version 2 with the classic case style which I've upgraded the OS on to AMS 2.09 (date, time, apps screen, but I have it load to the home screen still since that's what I use the vast majority of the time).

I also downloaded the OS from my calculator to my computer and run it in an emulator for kicks.

I use it for both the mundane and more advanced calculations and algebraic equation manipulation I do on a regular basis.

Re: What's your EDC Calculator?

I'm awaiting delivery of a Casio FX-9750 GII. I hear it's what all the kids are using these days.
I have to go back and learn again all that stuff you learn in college, algebra, calculus, quadratic equations, etc.

Re: What's your EDC Calculator?

Yeah, I don't graph stuff on my calculator too often, but I do use the CAS on it regularly.

I use 4 AAA Eneloops in it. I'd like to recharge them with PV solar eventually (mostly for fun, or to have available in an emergency along with HAM radio equipment). Not really a priority though since the electricity used by recharging my batteries is insignificant in comparison to how much electricity me and my wife use on a regular basis for everything else.

Re: What's your EDC Calculator?

My cellphone's calculator isn't good enough to cover all me needs.

I'm thinking about upgrading to a "smarter" Epic 4G (I like the qwerty keyboard with separate numbers) soon and getting SpaceTime for it once it becomes available to Android users. We'll see. For now my TI-89 does the job, and it stays charged a whole lot longer than any cellphone I know of does. I also kind of like the classic look and feel of it and its ease of use. (I'm a fan of real buttons, though touch screens are nice to use like a computer's mouse.)

Re: What's your EDC Calculator?

Go ahead and giggle Casio 506 watch:

I have a smartphone, laptop and electrical conversion calculator at work. But, I still wear this one. Very water resistant and cheap.
I spend too much time at work in really confined, grimey spots. In those cases, I don't wear any watch or phone, etc.
These are pretty good watches for the price and utility.

I'm guilty of getting a Timex pager/e-mail watch several years ago. I might have also had a calculator watch for a short time many years ago. If not, I'm pretty sure I at least wanted one for a while. That would have been something like 25 years ago.

Re: What's your EDC Calculator?

I completely understand the "stigma" surrounding the old, geeky calc watc. Really dated(bad pun intended). I have recently restarted a small collection of calculators and slide rules. One of my still functioning favorites is a early 70's Commodore with red leds .

Imagine being able to do serious computation without needing

(c) to "clear error" because you mis-typed a number and risk your whole computation being lost.

There are other, more subtle advantages, but for regular calculator use, I think those are the top three.

It takes all of 10 minutes of experimentation to get used to RPN, I don't know why it isn't more common.

Re: What's your EDC Calculator?

Yeah, I've heard of some of its advantages. It's kind of like you do the calculation in different layers. It would be difficult for me to keep track of which layer I was on, at least until I got used to it.

I just enter in a whole equation on my calculator and it returns the most simplified result, or solves for any/every variable. I do have to use parenthesis and whatnot though.

Got some old style calculators too, from an ancestor. Both are about approx 70-80 years old, got an addition and a subtraction function and are still working fine.

The Supra has been more for the brief case or the desk, the smaller one with the leather case in the third pic is very well pocketable, and has obviously been used quite often.

Re: What's your EDC Calculator?

Wow. That is definitely pretty cool; even more so since they were passed down in your family.

Thanks for sharing.

I wish I had my grandparents' old mechanical typewriter. I would go over to their place to use it when I was in elementary school. It was old then, but worked perfectly, so long as you didn't hit more than one letter at once, causing the strikers/hammers (or whatever they're called) to hit each other. Don't know what ended up happening to it.
